RAT'CHET GUIDE AND SUPPORT y.A]; p1ication led April 24, 1931. Serial No. 532,663.

This invention relates to. an improved ratchet guide and support and one object of the invention is to provide a device ot this character by means of which a ratchet carry- ``5 ing a bit may be supported in an operative position for boring an opening through a joist and so guided that a straight opening may be bored throughla joist at a desired angle.

Another object of the invention is to so mount theguide that when boring openings through a number of joists in a Wall the openings may be formed in axial alinement with each other and thereby permit a pipe to ex- Yi tend ina straight line and have proper lit in all of the openings through which it passes. Another object of the invention is to so construct the ratchet guide that it may be used in connection with pipes of various standard diameters and to also permit the device when in use to serve not only as a device to support and guide a ratchet while boring a hole in a joist but also permitted to be employed as an indicator to form a mark upon t" a side of a joist and indicate the proper location for an opening to be bored through the same.

Another object of the invention is to permit a pipe serving as a carrier for the sup- ,o port and guide to extend through openings already formed in twoor more joists thereby insuring boring of an vopening in another joist at the proper angle and also permitting the pipe to be moved longitudinally and "335 properly advance a bit as an opening is bored.v

Another object of the invention isto not only permit a pipe to serve as a carrier for the ratchet guide and support but also serve '40 as a hand hold which may be grasped by a The invention is illustrated in the accompanying dra-wing wherein:

Figure 1 is a view partially in section and partially in elevation showing the ratchet support engaged in a pipe to pass through openings formed in a pair of joists. s Figure 2 is a view similar to Figure 1 showing the device moved into position to engage a joist and indicate the position at which an opening -is to be bored therein.

Figure 3 is a View showing a tool of the ratchet type and carrying a bit by means of which an opening has been formed through a joist.

Figure 4 is an enlarged view looking at one end of the improved ratchet support and guide.

Figure 5 is a side elevation thereof.

Figure 6 is a view showing the improved ratchet guide and support partially in longitudinal section and partially in side elevation, and

Figure 7 is a sectional view taken along longitudinally through one ot the sleeves forming part of the improved device.

This improved ratchet support and guide is intended to support a tool hold-er 1 of the ratchet type having an operating handle 2 and adapted to carry a bit or auger 3 by means of which an opening 4c is to be formed in a joist 5, which may extend vertically ot the wall or serve as a ceiling beam. When erecting a building thewall joists or ceiling beams 5 are spaced transversely from each other and in order to support pipes forming part of the heating or plumbing system or as conduits for electric wires it is customary to form openings through the joists.

The pipes should tit snugly in the openings in order that they may be well supported and pipes used for hot water or steam heating should extend at an angle instead of horizontally. The openings formed in the joist should be in'alinement with each other so that a pipe may be easily passed through the openings. v

The improved ratchet guide and support indicated in general by the numeral 6 has engagement with the tool or bit holder 1 as shown in Figure 3 and is engaged in a pipe 7 which may be of any length desired but should be at least of sufficient length to engage through openings formed in two joists and project from the same as shown in Figure 1. This pipe will of course be of the same diameter as the pipe which is to be mounted in the openings formed through the joists. By this arrangement openings of the proper diameter to receive a pipe may be formed in the joist and by moving the pipe longitudinally through the openings already formed a spur 8 at one end of the guide may be brought into contact with the next joist to be bored as shown in Figure 2 thereby accurately marking the j oist so that an opening may be formed therein in axial alinement with openings already formed in other joists.

The guide or support has a shank 9 which is circular in cross section and at one end of the guide is formed a squared end portion or head 10 from the outer end of which projects the spur 8 located centrally thereof. A collar 11 is formed about the guide between the shank 9 and the head 10. The shank of the guide is of a diameter permitting it to fit snugly within a pipe of the smallest diameter generally used and therefore when a small pipe is to be employed the guide may be fitted into one end of a short length of pipe and the flange 11 will bear against the end of the pipe. After an opening has been bored in one joist a length of pipe which is quite short is engaged through this opening and moves forwardly until the spur 8 bears against a side face of the next joist to be bored. This marks the position at which an opening is to be formed in the second joist. The pipe is then withdrawn a sufficient distance to permit the ratchet wrench 1 to be engaged with the head 10 and bear against the shoulder 11 and the spur 12 of the bit or auger is engaged with the mark formed by the spur 8. The pipe is held by one hand in order to apply pressure to urge the bit toward the joist to be bored while at the same time the handle 2 is actuated to rotate the bit and form an opening through the joist. After the second openingfis formed a longer pipe is used. This pipe should be of sufficient length to engage through the openings bored in the two joists and be moved 'forwardly a sufficient distance to mark the next joist without moving entirely out of the openings in the two joists through which it extends. It will thus be seen that the pipe which serves as a carrier for the guide will be well supported in openings formed through two joists and will constitute a convenient hand hold for a workman standing upon a step-ladder or other support while boring an opening through a third joist. The fact that the pipe engages through two openings will also serve to'prevent it from having side play and moving out of its proper angle which may be either horizontal or at an incline.

When the tool holder and guide is used in connection with a pipe of a larger diameter it should still have snug fit within the pipe and be retained in axial alinement therewith and in order to do so there has been provided a number of sleeves 13 which fit about the shank 9 of the guide one within another as shown in Figure 6 and each sleeve is formed at its forward end with an outstanding annular flange 14 serving to limit sliding movement of the sleeve one within another in one direction and also serving to engage an end of a pipe.

It will be understood that each sleeve has an external diameter correspondin to the internal diameter of a pipe of a stan ard size and therefore by applying the proper number of sleeves about the shank they may serve as bushings to snugly fill the interior of the pipe and cause the tool guide to be disposed in axial alinement with the pipe. It will thus be seen that the device may be used in connection with pipes of any standard size and openings formed through joists which will be of the proper diameter to snugly receive a pipe and so alined with each other that the pipe will extend at the proper angle. It will also be noted `that when this device is in use the bit may be held in engagement with a joist to be bored and proper ressure applied to feed the bit forwardly as tlie opening is bored.

From the foregoing description ofthe c011- struction of my improved invention, the operation thereof and the method of applying the same to use will be readily understood. It will be seen that I have provided a simple, inexpensive and efficient means for carrying out the objects of the invention.

vWhile I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form7 proportion and in the minor details of construction may be resorted to, without departing from the spirit or sacrilicing any of the principles of the invention.

Having thus described the invention what is claimed is:

In a means for guiding and holding a ratchet tool, a plurality of telescoping sleeve members, each provided at its forward end with a peripheral flange adapted to abut the peripheral edge of the next encircling sleeve, said flanges being stepped with relation to one another when the sleeve members are assembled and limiting the movement of the respective sleeves in one direction, a cylindrical shank fitting snugly in the inner telescoping sleeve member provided with a squared tool engaging outer end portion adapted to project beyond the forward end of the last mentioned sleeve, said squared end portion terminating in a Spur, and a circumferential flange formed integral with said shank at the junction of the squared portion with the body of said shank, said latter flange being adapted to abut the forward peripheral edge of the inner sleeve to limit movement of said shank in one direction and also complete the stepped sequence ofthe aforesaid anges.

In testimony whereof I affix my signature.
